Remove the local ${PYTHON} python (and python3) variable definitions from
the *** Variables *** sections of all affected robot files. These local
definitions were overriding the pabot-injected venv Python path passed via
--variable PYTHON:/path/to/venv/python, causing tests to use the system
Python (which lacks required packages like structlog, sqlalchemy, etc.)
instead of the nox venv Python.
The correct ${PYTHON} value is already set by Setup Test Environment in
common.resource via sys.executable, and pabot passes it via --variable.
The local fallback definitions are redundant and harmful in parallel runs.
Audit found 56 robot files with the pattern (more than the 9 originally
identified in the issue). All occurrences have been removed.
ISSUES CLOSED: #1309
TDD expected-fail tests proving bug #822 exists:
CheckpointService.rollback_to_checkpoint() returns a successful
RollbackResult but does not execute git reset --hard. Files modified
after the checkpoint remain unchanged after rollback.
Also fixes Robot Framework timeout robustness across the entire test
suite: all Run Process calls now use on_timeout=kill (prevents
SIGTERM-induced -15 exit codes under CI load) and timeouts increased
to 120s (prevents premature kills during heavy parallel execution).
ISSUES CLOSED: #839
